Enjoy today because tomorrow we turn on the afterburners as mid-90s pay us a visit. I think the “blue moon” tomorrow night should be more aptly named a red one. The heat makes for an authentic send off to the last weekend of summer, at least by some measure. The only problem comes from whatever is left of Isaac which could arrive here as early as Sunday but hopefully holds off until Monday. For you lucky souls headed to the beach, we have an outlook at the end of this forecast.

Today (Thursday): Sunny skies and limited humidity make for a fine day. Temperatures climb quickly though and while most of us top out in the upper 80s, a few may hit the 90 degree mark. Breezes are light from the south. Confidence: High

Tonight: The blue moon (second full moon of the month) rises majestically as skies remain clear. Temperatures slip to the upper 70s to lower 80s for an outdoor kind of evening. Breezes quickly calm. Lows end up in the mid-to-upper 60s, but hold in the lower 70s downtown. Confidence: High

Tomorrow (Friday): The sunshine is not quite as friendly as readings are on their way to the low-to-mid 90s in nearly all locales. Light winds from the west offer little relief but at least humidity is still fairly moderate. The good news is no weather problems for the holiday dash to wherever. Confidence: High

Tomorrow night: The stars are unfettered and should be atwinkle given the still warm evening readings in the 80s. Lows end up in the upper 60s to lower 70s. Confidence: High

A LOOK AHEAD

Saturday should be dry and quite warm and if you have options today is the day to schedule the outdoor activities as the following two days look more iffy in the rain department. High clouds from Isaac’s leftovers in the Midwest may start to filter and a few pop-up clouds in the afternoon do little to abate the heat. Look for highs in the low-to-mid 90s yet again. Evening readings will be in the 80s as humidity levels start to climb. Overnight lows end up mainly in the low-to-mid 70s. Confidence: High

Sunday could still pull off a surprise and the clouds from Isaac’s moisture could stay put in the Midwest. However, knowing our luck, not only will the clouds start increasing but also a few showers and thunderstorms could begin to bubble up in the late afternoon (40% chance). Highs should at least be set back to the mid-to-upper 80s but humidity is likely to be on the rise big time. Additional thunderstorms are possible overnight with a 50% probability. Lows reach the low-to-mid 70s as the air has the feeling of the tropics by this time. Confidence: Low-Medium

Labor Day (Monday) is more likely to harbor plenty of showers and thunderstorms (60% chance). These are likely to be tropical in nature, meaning some intense downpours with gusty winds when it is raining. Plan for some travel challenges if you are headed back home. Highs reach the low-to-mid 80s. Confidence: Medium

Beachcast: There will be little difference in weather conditions for the beaches from northern North Carolina and Virginia up through southern New Jersey this weekend. Highs will be in the upper 80s to lower 90s on Friday and Saturday under sunny skies. Clouds should start to increase on Sunday with a 30% chance of an evening thundershower. Highs should be lower 80s north to upper 80s south. There will be a 60% chance of showers and thunderstorms on Monday. Highs range from lower 80s north to upper 80s south once again. Wave heights in most areas are likely to only be 1-2 feet and water temperatures are generally in the mid-to-upper 70s.
